The Testo 420 measuring instrument enables you to measure flow velocity, volume flow, absolute pressure, temperature and relative humidity. The automatic zeroing function ensures higher accuracy for low pressures.
All measuring values are easy to read on the large display which has an illumination function. For analysis and documentation, measurement data can be saved and measurement protocols can be created directly on site using the testo 420 App. In addition the measurement data can be easily accessed via PC without any additional software thanks to the plug & play function.
The Testo 420 volume flow hood with its integrated measuring instrument was not only developed to measure volume flow measurement. The measuring instrument can also be taken off the hood and used to measure pressure, flow and volume flow measurements in a duct. Simply attach a Pitot tube and connection hoses (both optional). With integrated, timed and multi-point mean calculation.
High measuring accuracy at swirl outlets thanks to volume flow straightener
Volume air flow is frequently measured at swirl outlets. Air flows are often incorrectly measured due to the turbulent air at these outlets.
The Testo 420 enables you to significantly reduce these measurement errors. The integrated volume flow straightener calms the turbulence and converts it into a virtually uniform air flow. This enables accurate calculation of volume flow in the 80 to 3,500 m3/h range.
Create protocols directly on site and E mail them using the Testo 420 App
Take advantage of further practical functions and download our free App. Because the App connection enables mobile devices such as smartphones and tablets to be used as a secondary display and as a remote control via Bluetooth.
The App enables live measurement on HVAC systems using a start and stop function and the saving of measurement data in txt format. You can create the measurement protocol directly on site using the App. Measurement results, such as the overall volume flow and the air exchange rate, can be directly assigned to customer-specific protocol templates. You can then send your readings and protocols via the e-mail function. This means you save a considerable amount of time and increase efficiency.
